Figure 1.

Number of total cells, neutrophils and macrophages in BALF from PPARα^+/+(+/+) and PPARα^-/- (-/-) mice exposed to LPS or saline. Data are mean ± SEM of n = 10–13 animals. Statistically significant differences at α = 0.05: (*) when compared to PPARα^+/+ mice treated with saline; (#) when compared to PPARα^-/- mice treated with saline; and ($) when compared to PPARα^+/+ mice treated with LPS.
